Foundry sand treatment mixing and rolling equipment

Abstract

The invention discloses foundry sand treatment mixing and rolling equipment comprising a machine base. The top side of the machine base is fixedly installed with a sand mixing pipe, one side of the sand mixing pipe is fixedly provided with a sand mixing box, the sand mixing box communicates with the sand mixing pipe, the top side of the sand mixing pipe is movably provided with an unloader, the two sides of the unloader are provided with fixed columns fixedly mounted on the top side of the sand mixing pipe, and the top ends of the two fixed columns are provided with stretchable grooves. The foundry sand treatment mixing and rolling equipment solves the technical problem that sand treatment technological indexes are incompatible in two different sand production modes of the automatic production line and the sand mold rack production line for casting enterprises, the cost of a sand mold rack is directly promoted to be greatly reduced, the casting cost is greatly saved, the bentonite andpulverized coal adding amount is reduced, raise dust in production is reduced, the first-line environment of the enterprises is improved, meanwhile, it is ensured that the product qualification rate remains at a high level, idling of a sand mixing machine can be effectively avoided, meanwhile, sand mixing is more uniform, and the quality of the sand is improved.

Description

technical field [0001] The invention relates to the field of foundry technology, in particular to a sand processing and mixing equipment in a foundry. Background technique [0002] With the rapid development of the manufacturing industry, the upgrading of foundry equipment is getting faster and faster. The traditional "stall" production mode has been replaced by sand mold production, vertical line, and horizontal automatic line production mode, but in the process of upgrading , the automatic line cannot completely replace the manual production mode. Therefore, the mixed production of the automatic production line and the sand mold frame has become the most economical mode for some foundry enterprises. The indicators and process requirements for sand treatment of the automatic production line and the sand mold frame production line are completely different. How to mix Satisfying the above two production modes at the same time in production has become a difficult problem to be...

AI Technical Summary

Problems solved by technology

The continuous sand mixer includes a machine base, a mixing device connected to the machine base and a sand feeding hopper connected to the mixing device. The mixing device includes a conveying sand mixing mechanism and a final mixing mechanism. One end of the conveying sand mixing mechanism is connected to the sand feeding hopper. The other end is connected to the final mixing mechanism; the outside of the conveying sand mixing mechanism and the final mixing mechanism are equipped with a temperature control cylinder, but this device cannot remind the staff to refill when the sand in the feeding box is filled, causing the machine to run idly , wasting resources, and at the same time only relying on directional rotation for sand mixing, so that the quality of the sand cannot be guaranteed
